Mr. Tom Ogilvy,

I made one Excel sheet where i need to use below formula in complete columns which increase the size of my work sheet, Is there why to put these formula in VB instead of formulas in excel to avoid such a big size of any file. It will be awesome if you guide me how to apply them in VB.

=IF(B16="","",IF(B16>=380,1,IF(AND(C15=1,B16>=362),1,0)))

=IF(C18="","",IF(C18=1,SUM(E17,1),""))

=IF(C16=1,((B16)*(B16))/25,"")

=IF(B18<0,AVERAGE(B17,B19),B18)

=IF(D18="","",IF(D18=1,(C18/$F$2)*C18,""))

Sarwar,

So you say you need formulas in an entire column - over 1 million cells.

You can certainly enter formulas by using VBA.

Range("D16").Formula = "=IF(B16="""","""",IF(B16>=380,1,IF(AND(C15=1,B16>=362),1,0)))"

will put your first formula in cell D16

You can put that formula all the way down column D with

After running that line of code, the last cell in column D had this formula

D1048576: =IF(B1048576="","",IF(B1048576>=380,1,IF(AND($C$15=1,B1048576>=362),1,0)))

D1 had D1: =IF(B1="","",IF(B1>=380,1,IF(AND($C$15=1,B1>=362),1,0)))

Note that since C15 refers to the row before B16, I have fixed it as an absolute reference. You can't start the formula in row 1 and refer to the cell above it. I am just providing this as an example because you have not explained a lot of anomalies in your formulas.

But this enters the formula in the column. You could then add code

Range("D:D").Formula = Range("D:D").Value

which will overwrite the formula with the values calculated.

so code like

Sub BuildFormula()

Range("D:D").Formula = "=IF(B1="""","""",IF(B1>=380,1,IF(AND($C$15=1,B1>=362),1,0)))"

Range("D:D").Formula = Range("D:D").Value

End Sub

Another approach would be to write code that loops through column D and performs the same calculation as your formula

Sub EvaluateFormula()

Dim i As Long

For i = 2 To 1048576

If Not IsEmpty(Cells(i, "B")) Then

If Cells(i, "B") >= 380 Then

Cells(i, "D").Value = 1

ElseIf Cells(i, "B") >= 362 And Cells(i - 1, "C").Value = 1 Then

Cells(i, "D").Value = 1

Else

Cells(i, "D").Value = 0

End If

End If

Next i

End Sub

Here I have preserved you formula including a reference to the row prior so I start the code at row 2.

All this said, you may still end up with a large workbook if you put data in a lot of cells.

The code I provided is representative because you have said nothing about where your formulas need to go or the values that your formulas would produce need to go.
